Cadillac's F1 entry under the brutal 2026 regulations demanded building a team from nothing across continents in record time. The General Motors Charlotte Technical Centre, a 130,000-square-foot facility near Hendrick Motorsports in North Carolina, became the backbone. GM's four full dynamic simulators and engineering software let the squad rehearse before facing established rivals. Veteran engineer Pat Symonds said they would not be here without that facility.

The team's Race Ready programme simulated 2025 grands prix in real-time with drivers like Simon Pagenaud, giving the 400-plus person squad vital reps. GM provided more than a simulator—it shared software like Race Vehicle Gateway and its vehicle performance group's expertise. Cadillac tapped into existing tools rather than building from scratch, which accelerated development far beyond what a start-up could achieve.

GM's involvement went beyond equity and marketing. The Charlotte facility housed aerodynamic and suspension testing tools, while personnel transferred knowledge across NASCAR, IndyCar and sportscar programmes. James Knapton, head of performance analysis, credited GM's pre-built simulation models for giving the team an immediate head start. Without that cross-series resource sharing, Cadillac would have needed years to reach race readiness.
